石落としについては、400年に渡って信じられてきた使い方とは違う新たな可能性を、実際の石落としを使った実験から検証し、本当の使い方に迫る。
In this episode, we approach the secrets hidden in Matsuyama Castle and follow a group of soldiers as they attack the castle, facing a 400-meter-long stone wall in the mountain, a doorless gate, a gate that enables ambushes, and the final defense at the tower keep. CG and drones are used to introduce the defensive features that await them. We also investigate the truth about ishi-otoshi or stone dropping chutes and their actual purpose.
